## API Reference

> Source set: Android

```kotlin
public val WindowInfo.isCrossWindowBlurEnabled: Boolean
```

Whether cross-window blur is currently enabled by the system.

Cross-window blur might not be supported by some devices due to GPU limitations. It can also be
disabled at runtime (e.g., during battery saving mode, when multimedia tunneling is used, or when
minimal post-processing is requested). In these situations, no blur is computed or drawn. Apps
should check this flag to fall back to alternative styling (such as adjusting scrim opacity or
changing themes) when blurs are disabled.

This affects both window blur behind (see
`android.view.WindowManager.LayoutParams.setBlurBehindRadius`) and window background blur (see
`android.view.Window.setBackgroundBlurRadius`).

On Android, this property queries `android.view.WindowManager.isCrossWindowBlurEnabled` on API
31+; on older API levels it always returns `false`.
